Answer:
Its the triangle.
Step-by-step explanation:
Tri:
(3[tex]\sqrt{147\\}[/tex]+2[tex]\sqrt{108}[/tex])+(6[tex]\sqrt{12\\}[/tex])+(2[tex]\sqrt{48}[/tex]+3[tex]\sqrt{75}[/tex])=68[tex]\sqrt{3}[/tex]=117.78
Square:
4(1/3[tex]\sqrt{63}[/tex])=4[tex]\sqrt{7}[/tex]=10.58 (four equal sides so multiply by 4)
Rectangle:
2(1/4[tex]\sqrt{100}[/tex])+2(2[tex]\sqrt{48}[/tex]+4[tex]\sqrt{75}[/tex])=5+56[tex]\sqrt{3}[/tex]=101.99
